The Schedulefrei'ened to in these fret-ters Patent andmaking part of thesame.

To all whom it 'may concern: i Be it' known that I, EDWARDL. J pNEs, ofMemphis, in the county of Shelby and State of Tennessee, have inventedanew and useful Improvement in Feedwater Heaters; and I do herebydeclare the following to'be a full, clear, and exact description of thesame, reference being h'ad to. thel accompanying drawing n1aking .'apart of this specification, in which-'- Figure 1 is a side elevation;

Figure 2, a rear elevation; and

Figure 3, a'plau Viewof the drum, receiving-pipe, and connectingfpipes'.f f

This invention -relates to certain improvements in that class offeed-water heatersfor steam-boilers in which'a pipe; or pipes arearranged to traverse the fnrnnce-chambe`r, through which pipes water issupplied to the boiler by a force-pump. The said'improvements consistinthe arrangement, hereinafter described, of a drum, placed below theheating-chamber, and connected with the boiler `by a vertical pipe orpipes; a pipe placed parallel, and

about at the same level, with said drum, and connect'- ed therewith byhorizontal tubes; and one or more pipes, coiled or serpentine 'in form,connecting the boiler and the aforesaid parallel pipe, and traversing,

inte1medi.1,tely, the furnace-char'nber.-v

Referring to the d rawingf A Aare boilers, and B, the furnace beneaththe boilers. A transverse drum, a, suitably supported beneath:the-furnace B-is connected with the boilers by vertical pipes, b.'

A- pipe', c, placed parallel with and in rear of the .drum a, isconnected therewith by horizontal crosstubes, d. The pipe c is providedwith a vertical cross-tube, e, through whichwater forced by the pumpenters.

Serpentine pipes, f, connect the boiler A and `pipe c, said serpentinepipes'traversing. the `furnace-chamber, and, when a tire is burningtherein, receiving a portion ofthe caloric that would otherwise bewasted, but which, by this arrangement, is utilized to the serpentineheating of the water within the pipes f, and the .more speedy generationof steam.

The pipe c is furnished with cocks, h, one at each side of the centraltube c.

, The cross-tubes el are each providedwith a cock, t', and cocks '7c areplaced,l one in each serpentine pipe f. -Vhen these cocks are all open,whatever water is contained in the apparatus seeks a level in thedrulnand pipes, the cross-tube c being provided with a valve whichV preventswater from escaping thereat.

At the time of starting adire in ,the furnace, the cocks should all beopen, in order that the pipes f may be iilled and receive the rstheating, the steam generated by which rises to the bbiler, enters thesame below the water-line, and, consequently, assisting to raise steamcnough'iuthe Vboilers to start the pumps by which water is supplied.`Ars soon as the pumps are in operation, the cocks 'i ofthe cross-tubesd should -be cl0sediu order that the water may be forced through theserpentine pipes f into the boilers. But, in case of fracture of one ormore ofthese pipes, or if they stand in need of repair, the cocks Vh ofthev pipes cvaud .the cocks k shouldbe closed, and the cocks'i opened,in order that water may be forced through the drum c into the boiler;

In case of accident to the pumps, the valves should all be opened in'order that the serpentine pipes may be filled, so as not'to be.injuredby re. The cocks k are to prevent the escape of-'water from vthe Vboileri when the pipes get outot'order.

Having thus describedmy invention, WhatI claim as new, and desire tosecure by Letters Patent, is r The arrangement of the drum a, vert-icalpipes b, straight pipe c, cross-tubes d, Vcocks h, i, Vand k, and pipesj, with the ,boiler Aand furnace,as specified. i EDWARDL.. JONES.
